https://community.extremenetworks.com/t5/data-center-vdx/brocade-vdx-6720-blocking-ips-until-reboot/m-p/6203#M95 Hey Everyone, <BR /> <BR /> I keep having this issues with our Brocade switch to where it blocks an IP until I reboot the switch. How can I see what is causing this or allow it without reloading the switch. <BR /> <BR /> Also when I reboot the machine connected to the switch, that is when it gets blocked. Then I reboot the switch and it comes back up.

If it's not on 4.1.3d firmware yet, I highly recommend upgrading to it, then verify if you still have the issue. <BR /> <BR /> If you still do, then please collect the data requested from above during the problem and after.
